TURN-TABLE.

Specification of Letters Patent.

Application filed December 2, 1908.

Patented Feb. 8, 1910. Seria1 No. 465,641.

To all whom it may concern.'

Be it known that I, HENRY R. STICKNEY, a citizen of the United States of America, and a resident of Portland,'county of Cumberland, State of Maine, have invented certain new and useful Improvements in Turn- Tbles, of which the following is a specification.

My invention relates to a turntable suitable for use in Iautomobile garages and it relates particularly to an improved construction of the device described in my Letters Patent N o. 813,462 issued Feb. 22, 1906.

In my original patent there was a central annular frame resting upon antifriction rollers, these rollers running on an annular track formed in the bedpiece. A pivoting pin extended upward from the bed through the annular frame and a ball bearing connection was provided between the annular frame and the upper end of the pin to receivethe upward thrust. The body of the table was composed of beams extending from this central frame to the outer edge of the turntable, these beams being trussed and covered with suitable planking.

I found in actual use that there is a serious objection in automobile garages to the use of wood ioors or anywooden construction which is liable to get soaked with oil and to accidentally take fire.

The object of my present invention is to provide a substitute for the plank covered body portion of my turntable which shall be absolutely fire proof, which may be cheaply made and easily built and strong and stiff in construction conforming to the concrete floors now in common use, and these objects I attain by the use of the device hereinafter described which consists essentially of an annular body or disk of reinforced concrete supported by the pivoted center constructed preferably as shown in my prior patent.

I illustrate my invention by means of the accompanying drawing in which is shown a turntable constructed according to my present invention.

.In the drawing, Figure 1 is a central vertical section and Fig. 2 is a plan with certain portions cut away and removed.

At A is shown the case constructed of an annular casting having an annular track on its u per portion preferably formed with side flanges whereby it may retain a quantit of oil for lubrication. Running in the track are the antifriction rollers b yjournaled to a suitable spider b. Resting on the rollers is an annular frame composed as here shown of a circular casting c which rests directly on the rollers and a circular ring J which embraces the casting c and is bolted to it.

'It represents the pivoting pin, e and f the thrust plates, g the bearin balls between the plates and l1.v the nut ho ding the thrust plates in position, these parts' so far described being essentially the saine as shown in my prior patent above noted, with the exception of the annular ring J.

The ring J extends .outside of the revolvin mechanism and to a point near the base of the pit, the lower portion of the ring inclining outward and belngl provided with an outward extending flange on its lower edge. 'The space between the ring J and the Outer edge of the turntable is composed of an annular disk of reinforced concrete the outer edge of the turntable terminating in a band y'z made up of angle iron having an inward extending flange at its lower edge. Reinforcing rods j 'are shown as connecting the upper portion of the ring J with the flange of the ring jz. As here shown, the outer end of each rod j is hooked into the flange and the inner end extends throu l1 the ring J and is secured in place by a sulte able bolt. Reinforcing rods j cross the rods 7" at intervals forming concentric rings which are wired or otherwise secured to the radial rods j at the points of intersection. The space from the ring J out to the band j2 is filled in with suitable concrete which 1s reinforced by lthe rods j ,and j already described.

The operating parts of the device are protected by an iron plate z' fitting in a rabbet formed in the upper portion of the rin J so that the plate comes flush with the sur ace of the concrete. In constructing the turntable the central working portion, is erected in the usual way in a suitable pit and the reinforcedconcrete is laid in place v in the usual, manner. The reinforcing rods are shown of straight iron but they m-ay be of corrugated or twisted iron or steel and they may extend through the mass of concrete in any direction to give the required strength.

While I have described and shown the central framework and the turning mechanism as constructed according to my prior patent, `it may be otherwise constructed while still giving the advantage of an an nular body of vconcrete forming the mam portion of the turntable.

1. The herein described turntable comprising a pivoted center and an annular disk of reinforced concrete secured to and supported solely by said center.

2. The herein described turntable corn- 4prising a central annular pivoted frame and turntable, radial rods connecting said frame with the outer band and a concrete filling between the frame and the band.

5. The herein described turntable comprisin a central annular pivoted frame, an outer and embracing the outer edge of the turntable, radial rods connecting the frame and the band and concentric annular-rods crossing said radial rods and concrete {illing between the frame and the band.

6. The herein described turntable -comprising a base having an annular track, rolls adapted lto run onsaid track, an annular frame resting on said rolls, a central pivoting pin extending vertically through said annular frame and an annular diskv of reinforced concrete secured tosaid frame.

7 The herein described turntable comprisi'rig a base having an annular track, rolls adapted to run on said track, an annular frame resting on said rolls, a-central pivoting pin extending from said base through said frame, an antifriction bearinv between said frame and the upper end ofa said pin to receive the upward thrust and an annular disk of reinforced concrete secured to said frame to forni the body of the turntable.

8. The herein described turn table comprising a central annular frame, an annular track for supporting said frame, means for resisting the upward thrust on said frame, a disk ofl reinforced concrete supported by said frame.

9. The herein described turn table comprising a central frame, an annular track for supporting said frame, means for resisting the upward thrust on said frame and a disk of reinforced concrete supported by said frame.

10. The herein described turntable coniprising a central frame, an annular track for supporting said frame, a pivoting pin for resisting the upward thrust on said frame and a disk of reinforced concrete supported by said frame.

11. The herein described turn table comprising a central frame, a pivoting` support for said frame and an annular disk of .reinforced concrete supported solely by said frame.

In witness whereof I have hereunto set my hand this 27th day of November, 1908.
